En route to a wedding celebration, the USS Enterprise is redirected to the Romulan homeworld. A civil war there has opened the possibility of a peace treaty with the Federation. And the new Romulan Praetor has arranged to have the Enterprise, and specifically her famous captain, Jean-Luc Picard, brought in to discuss the future of the galaxy. No more Neutral Zone? An end to centuries of hostilities dating back to the first encounter with the Romulans? Is this too good to be true?

Picard, Riker, Data, Worf, La Forge, Crusher, and Troi are prepared to negotiate a peace treaty. But upon their arrival the crew is faced with a threat that could lead to the destruction of the planet Earth. And Picard encounters the man who could be his most dangerous adversary yet - and a surprisingly personal nemesis.
